Be it known that I, 'IULIUS JACOB, of the city and State of New York, have invented, made, and applied to use a certain new and useful Improvement in Umbrellas; and I do hereby declare the following to be a full, clear, and exact description of the said invention` reference being had to the annexed drawing, making part of this specification, wherein- Figure 1 is a section of an umbrella spread containing my improvements.

Figure 2 is a section showing the frame in a folded condition.

Similar marks of reference denote the same parts. Y

Umbrellas have heretofore been made to fold for the convenience of travellers, so that such umbrellas may he carried in a valise or carpet-bag.

The natureof Vmy said invention consists in constructing the ribs of umbrellas so that one part slides into the other, so that they can be shortened up for transportation or drawn out fernse, in combination with a handle that is made of pieces jointed together'so that after the umbrella has been folded thehandle can also be folded.

In the drawing, a represents the rst joint of the handle; is the second, and c the thirdjoint, connected together by links, and provided with sliding-sleeve tubes d and a, that nstitlen the joint when the handle is straight. This construction allows the handle to be folded up short, as' seen in g. 2. z'is the crown of the umbrellato which the ribs are connected. /c is the stretcher, and Z the traveller or runner to which the stretchers l: are jointed. Each rib is made of a wire, m, with an eye at one end receiving the wire of thecrowu i', and passing at the other end into the tube 11 that is slotted on one side, in which a projection on the end of the wire mtravels so as to connect the parts and allow; the rib to be shortened by pressing the tube n down over the wire m. To the end of this tube 1t the stretcher 7c is jointed by ears, as shown, and I employ a second tube, o, into which the tube n, passes, said tube c having a longitudinal slot in Vone side, in which is a projecting piece from the tube n, so that these also are connected, but can be slid together into a small compass, as seen in iig-2, the ribs closingr into about one-third their length when distended. I provide crooks or handlesp at the ends of the tubes o,

that enable me to draw the tub-cs out with facility when the umbrella is to be distended. The umbrella is tobe provided -with any suitable covering; I prefer the thin vulcanized India rubber. The same is to be attachedI at the outer ends of the tubes o and at the crown z. The covering may also be connected near the inner ends of the tubes 0.'

When the umbrella is to be used, the handle is :first turned out straight, and stii'fened, and then the ribs are extended and the cover stretched by seizing the tubes o and handlcsp and drawing' them allbodily along thc handle. The umbrella is then ready for use in the usual manner. The reverse movement reduces the umbrella to a compact, short condition, as in fig. 2. More than two sliding-tubes n o may be employed, if desired.

What I claim, and desire to secure by Letters Patent, is

The umbrella-ribs formed of the sliding-tubes, as shown, in combination with the folding handle and strctchers, as set forth.

In witness whereof I have hereunto sctiny signature this ninth day of May, A, D. 1867.
